WASHINGTON (AP) — The Federal Reserve says it will begin circulating a redesigned $100 bill this fall, more than two years after its initial target.

The Fed has set a new target date of Oct. 8. The redesigned note incorporates added security features, such as a blue, 3-D security ribbon and a disappearing Liberty Bell in an inkwell. The features are designed to thwart counterfeiters.

The revamped bill had been expected to go into circulation in February 2011. But in December 2010, officials announced an indefinite delay. They said they needed more time to fix production issues that left unwanted creases in many of the notes.
